MEANS FOR PROTECTING AND APPLYING INGANDESCENT MANTLES.

Specification of Letters Patent.

Patented Jan. 15, 1907.

" with inverted burners.

The object of my invention is to rovide a construction including a receptac e which Will not only protect the mantle efliciently during storage or shipment, but will also serve as a convenient means for properlyapplying the mantle to a burner.

The invention will be fully described hereinafter and the features of novelty pointed out in the appended claims.

Reference 1s to be had to ing drawings, in which' Figure 1 is an elevation with parts in sec tion, illustrating the use of the receptacle in the act of applying the mantle to a burner; and Fig. 2 1s a vertical section through the receptacle, the mantle being removed therefrom. I

In Fig. 1 I have shown the tapering lower part A of a mixing-chamber or regenerative chamber, which receives a supply of gas and the accompanyair and delivers such gas-and-air mixture to the burner-tip A, formed with an external spiral rib A This spiral rib is adapted to be engaged by an internal spiral flange B upon a mantle-holder which has outwardlyprojecting' arms B for mani' ulating the mantle-holder, and downward y-projecting arms B upon which the edge of the inverte mantle C is secured by means of a cordD, the edge thus being spaced from the burner and also from 'thebody or ring B at the up er portion of the mantle-holder. These eatures of the burner and of the mantle-holder form the subject-matter of other ap lications filed" by me in the United States atent Oflice and are not claimed herein. It will be understood that the mantle-holder and the mantle are ermanently connected with each other, and heretofore the mantle was applied by holdin the outwardlyrojecting arms B between file fingers, and t us screwing the holder upon the burner-tip. This operation is objectionable in practice, not

upper end of the linin only because the proper centering of the mantle-holder may; be .fmissed, but chiefly for the reason that it exposes the mantle to contact with the hand, and thereiore to injury. To overcomepthese difiiculties, I have provided the special receptacle or box which in combination with the mantle-holder and mantle forms the subject-matter of my present application. The said box comprises an outer shell E the internal diameter of which at the top is such as to correspond to that of the holder at its widest portion-that is, at the arms B". The ends of these arms should fritit'ionally engage the inner surface of the shell E. A shoulder is formed on the inside of the shell for the arms B to rest on, and the simplest Way of forming such a shoulder consists in slipping loosely into the shell a lining F, which is shorter than the portion of the shell above the bottom G. Of course, if desired, the lining F may be glued or otherwise secured to the shell; but I find that such fastening is unnecessary. The bottom G, Iprefor to arrange not at the lower edge of the shell E, but at some distance therefrom, so as to stiffen the said shell at the point where it receives the pressure of the hand when grasped, as shown in Fig. 1. The bottom may be provided with a flange G, lining. the

lower portion of the shell E. A cover His.

fitted on the upper portion of the shell.

Durin storage and shipment the upper ends of t e arms B engage the inner surface of the shell E, theshoulder formed by the F preventing the holder from being pushe in so far as to bring the mantle G in contact with the bottom G. The mantle C is therefore freely suspended out of contact with any part of the box. When it is desired to apply the mantle to the burner, the lid or cover H is removed, and the, open end of the receptacle is brought over the burner-tip A so as to engage the spiral flange B with the spiral thread or rib A of the burner. Then by turning the box or receptacle in the pmper direction the box while the mantle-holder is being screwed on.- After the mantle holder has been screwed home the box can be separated from the mantle-holderby a longitudinal pull,

IIO

assisted, if necessary, by 'a turning movement in the same direction. as in screwing the mantle-holder on.

As illustrated, the mantle is applied in an inverted position. Idesire it to be understood, l1owever,-that it may be preferable to a )l the mantle in an upri ht osition-* Pl 3 g P prefer to employ some stop which will limit the inward movement of the arms B so as to absolutely prevent contact of the mantle O with the bottom G of the box.

What I claim as new, and desire to'secure by Letters Patent, is-

1. The combination, with a mantle holder having outwardly-projecting arms and a mantle secured toisaid holder, of a receptacle comprisin a shell, the inner surface of which is adapted to be frictionally engaged by the outer ends of said arms, a bottom arranged I The inner lining F may be omitted from the shell, although I within the shell at a distance from the loweredge thereof, an inner lining arranged within the shell to within a distance of its upper edge, so as to form a stop limiting the inward movement of said arms, and a cover for the upper end of the shell.

2; The combination, with the mantle and a holder extending outwardly beyond the largest diameter of the mantle, of a receptacle comprising a shell, the inner surface of which is adapted to be frictionally engaged by the outer portion of the holder, and a stop arranged within said shell to limit the inward movement of the holder. 7 r i 35. The combination, with a mantle and a holder to which said mantle is secured, said holder having a portion projecting outwardly beyond the largest diameter of the mantle, of

a receptacle adapted 'to contain said. mantle I and holder, and having its inner surface of such diameter as to frictionally engage the outer portion of the mantle-holder.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
